“One of the students snuck several cookies into school and had ingested them with a friend,” police said in a news release. “Both senior students … became ill and were transported to a local hospital where they remained overnight for observation,” the release goes on.

Police say a parent with a medical cannabis license had made the cookies and they were taken without consent.

The Children’s Aid Society is expected to conduct a review, according to police.

“Officers have also taken the time to educate students, parents, caregivers and teachers about the dangers and risks of consuming psychoactive chemicals at such an early age,” the release states.

Durham District School Board also confirmed the incident in a news release.

“The student who brought the cookies and a friend exhibited signs of consumption and impairment, and were taken to hospital where they were monitored for elevated heart rates,” the school board said.

“Recent legislation has not had a significant impact on how schools are dealing with incidents involving cannabis,” the school board added.
